Yes, it is possible mo matter what, if you are on older firmware...

Great!

Wondering if someone could point me to a guide on how to downgrade to oreo and unlock the bootloader on the 7 Plus?

No need to downgrade. Open developer settings. Disable and re-enable it. You can enable OEM unlock

Help, I want to Relock my Bootloader

Hi All,
I want to relock my Bootloader on my Nexus 6 running Nougat N6F26U. Has anyone relocked on Nougat?

Hello... Why do you specifically ask about Nougat? Unlock/relock is not firmware dependant..
Something to read just in case you didn't find it when you searched: https://forum.xda-developers.com/nexus-6/general/guide-safely-lock-bootloader-android-5-1-t3067302
Good luck...

And why do you want to relock? Paranoid about security? Keep your phone in your pocket.
All advice in XDA is not to relock your bootloader because it reduces the possibilities of recovering if you ever make a mess of an update.

Thanks for the reply, I read it and didn't know if it would work on Nougat.

Just install a custom Kernel that "kind of" hide your unlocked bootloader. EX Kernel, Franco and some others will be just fine. Android Pay will work... I would never lock the bootloader of mine, except for RMA purpose. If something fails, you have way more chance fixing it..! :good:

Yeah don't worry, it's still a Nexus
RacerXO - did you get Android Pay to work on the N6F26U Build? I also cannot get the bootloader to relock. I tried using WugFresh Nexus Root Tookit v2.1.9.
Did you install a custom Kernal? Wondering if this the answer. Thanks for the help.
I was unlocked from the first day I got the phone. Today I am locked, running nougat. Having read some of the horror stories here, I've always booted the phone after flashing updates before rooting. Did the same thing when I went back to stock to use AP. I backed everything I wanted to keep and made sure it booted, before I locked the bootloader. No issues after almost a month.
What I wound up doing was go to the T-Mobile page and established the official latest factory image was 6.0.1 MMB29K - installed that using Wugfresh. After installing and logging into WiFi and my Gmail account was prompted to install 7.0.0 NBD92G - this installed fine and then after installing a couple of security updates (thru April 2017) was able to Re-Lock my Bootloader (I wanted Android Pay to accept my credit cards). Data reception is still degraded significantly, am now thinking there is a problem with the tower.

Rooting with Magisk then using Magisk manager to "hide" root should give you android pay again. This may not be the directing you want to go in, but it is an option.
I locked Bootloader but you have to flash stock recovery 1st
I was on stock 7.1.1 unlocked bootloader, rooted Nexus 6.
I relocked my bootloader by simply going into adb/fastboot and flashed the latest stock factory firmware image (not the ota) with the June 5, 2017 security update, rebooted, activated developer options and enabled usb debugging, adb/fastboot again, and entered the command "fastboot oem lock", hit okay/yes when I got the relock warning, and voila! phone relocked.
Rebooted and set up phone/reinstalled my apps, music, and files.
No issues.

As far as I know if you are running a custom boot image you won't be able to relock the bootloader on nougat. It's a feature to prevent you soft-bricking your phone, because if you lock it and it detects unauthorised firmware it will refuse to boot.
To relock nougat, simply use the dload method to get a completely stock device and you will see that the bootloader is now relocked.

Two days ago I flashed B163C432 Firmware downloaded from https://androidhost.ru via dload folder and it locked my bootloader as usual, and I unlocked with my code without issues.

will we ever get a Nokia 8 custom ROM?

The official bootloader unlock method has been out for a while. Its almost 2 years since the phone has been released. I was hoping by now maybe some developer would have picked this phone up and put it to use. Is there a reason why nobody has bothered to start development on this phone and build a custom ROM? I think this phone has great potential given its specs and price. It would be nice to so further customizations beyond those allowed by rooting the phone.
I could do it too if I had any amount of knowledge about Android development, but sadly im a noobie.
What are your thoights?
It's not possible I guess. And Nokia has locked down. Unlocking bootloader. I have Nokia official app and it says Device not support.

No, Nokia hasnt locked it down. The bootloader unlock method only works up to the November Oreo security update. Just downgrade to Oreo November security update then unlock the bootloader, and then upgrade back to Pie.

Unlock bootloader on Pie?

Hello everyone,
I see that there isn't a way to unlock bootloader in Pie. The only way is to rollback to Oreo and will be unlocked by cmd commands or is there another way?
After that can I go back to Pie with bootloader unlocked or no?

Yes, you can update OTA to pie afterwards.
